Description

Technical Field

[0001] The present invention relates to the technical field of life care products, in particular to a shaving device with a quick-connect structure. Background Art

[0002] Shaving devices, such as razors, generally have a power unit and a working head. The output shaft in the power unit is connected to the working shaft of the working head, so that the working shaft in the working head is driven by the power unit to rotate, thereby driving the blade to move. To facilitate cleaning or replacing the working head, existing razors generally have the working head and the power unit detachably connected. Chinese patent CN106671146B discloses a detachable floating razor, wherein the working head is protrudingly provided with a clamping member 43, and a positioning block 47 is protrudingly provided on the circumferential outer side of the clamping member 43. The power unit is provided with a floating member 4, and the inner surface of the floating member 4 is provided with a dislocation slot 45 and a positioning slot 44. The positioning slot 44 is protruding with a positioning bolt 46. When the working head and the power unit are connected, the positioning block 47 first enters the dislocation slot 45, and then the clamping member 43 rotates a certain angle, so that the positioning block 47 enters the positioning slot 44 and passes over the positioning bolt 46 to achieve a locking connection with the positioning bolt 46. After repeated use, the positioning block 47 and the positioning bolt 46 are easily worn due to the rigid contact between the positioning block 47 and the positioning bolt 46, thereby causing the clamping to fail and causing the working head to easily fall off from the power unit. Summary of the Invention

[0003] In view of this, the present invention provides a shaving device with a quick-connect structure to solve the above technical problems.

[0004] A shaving device with a quick-connect structure comprises a quick-connect assembly and a shaving unit disposed at one end of the quick-connect assembly. The quick-connect assembly comprises a quick-connect housing and a connector disposed in the quick-connect housing. The quick-connect housing comprises a housing and a connecting sleeve disposed on the housing. The connecting sleeve comprises a receiving tube, at least one set of limiting portions disposed near one end of the receiving tube, and at least one clamping block disposed at the other end of the receiving tube. The connector comprises at least one clamping portion, at least one avoidance portion disposed on a side wall of the connector and connected to the clamping portion, at least one positioning protrusion disposed on one end of the clamping portion, at least one positioning groove disposed on one side of the positioning protrusion, and at least one clamping protrusion disposed on the opposite end surface of the avoidance portion. Each clamping portion comprises at least one guide groove and at least one clamping groove. The shaving unit comprises a quick plug. The quick connector includes a quick connector body, at least one first guide groove provided on the quick connector body, at least one second guide groove communicating with the first guide groove, and at least one stopper protrusion provided on the second guide groove near the first guide groove. When the stopper protrusion abuts against the engaging protrusion in the connector, the clearance portion elastically deforms, allowing the stopper protrusion to more easily pass over the engaging protrusion and engage with each other.

[0005] Compared to the prior art, the present invention provides a shaving device with a quick-connect structure. By installing the connector into the quick-connect housing, the quick-connect housing protects it from direct exposure, thereby improving the overall strength after assembly. A push ring, limiting ribs, reinforcing ribs, and a snap-in block are provided within the housing to limit the axial movement and circumferential rotation of the connector. Two snap-in protrusions are provided on the clearance portion. The clearance portion elastically deforms when subjected to force, reducing wear on the snap-in protrusions when the limiting protrusions pass over them, thereby extending their service life.

[0010] The following is a further detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0011] like Figures 1 to 4 , which is a schematic diagram of the structure of a shaving device with a quick-connect structure provided by the present invention. The shaving device with a quick-connect structure includes a quick-connect assembly 10, a shaving unit 20 plugged into the quick-connect assembly 10, and a power unit 30 disposed within the quick-connect assembly 10. It is conceivable that the shaving device with a quick-connect structure may also include other functional structures, such as edge chamfering, etc., which are well known to those skilled in the art and will not be further described here.

[0012] The quick-connect assembly 10 includes a quick-connect housing 11 and a connecting member 12 disposed in the quick-connect housing 11 .

[0013] The quick-connect housing 11 includes a housing 13 and a connecting sleeve 14 disposed on the housing 13. The housing 13 encloses the connecting member 12, protecting it from damage by the shaving unit 20 during use and thus extending its lifespan. The housing 13 can also be combined with a lower housing (not shown) to form a closed structure to protect the power unit 30.

[0014] The connecting sleeve 14 includes a receiving tube 141 integrally formed with the housing 13 , and at least one clamping block 144 disposed on one end of the receiving tube 141 .

[0015] The accommodating cylinder 141 is integrally formed with the housing 13 to improve strength. The abutting ring 142 is provided on one end of the accommodating cylinder 141 and abuts against the shaving unit 20 after installation. The following description will be made in conjunction with the shaving unit 20.

[0016] A push ring 142 is provided on one end of the accommodating tube 141, and at least one limiting portion 143 is provided on the end face of the push ring 142 facing the accommodating tube 141. The push ring 142 can play a role of radially fixing the connecting member 12. It is conceivable that in some cases, such as when the shaving unit 20 needs to swing, the push ring 142 may not be needed. One end face of the limiting portion 143 is flush with the inner side wall of the push ring 142, which increases the strength of the push ring 142 and prevents the push ring 142 from deforming when subjected to force. The limiting portion 143 is used to plug in the connecting member 12 and prevent the connecting member 12 from rotating during use. The limiting portion 143 plays a role of circumferential limiting on the connecting member 12, which will be described in detail below in conjunction with the connecting member 12. The number of the limiting portions 143 can be set according to actual needs. In this embodiment, there are two limiting portions 143 , which are symmetrically arranged on the end surface of the accommodating tube 141 .

[0017] The connecting member 12 includes at least one clamping portion 121, at least one avoidance portion 122 arranged on the side wall of the connecting member 12 and connected to the clamping portion 121, at least one positioning protrusion 123 arranged on one end of the clamping portion 121, at least one positioning groove 124 arranged on one side of the positioning protrusion 123, and at least one clamping protrusion 125 arranged on the opposite end face of the avoidance portion 122.

[0018] The number of the clamping parts 121 is set according to actual needs, such as the strength or diameter of the connecting member 12. In this embodiment, there are two clamping parts 121. Each clamping part 121 includes a guide groove 1211 and a clamping groove 1212. When the number of the clamping parts 121 is multiple, each guide groove 1211 is set corresponding to the clamping block 144, and an inclined surface transition is set between the clamping block 144 and the clamping groove 1212, so that the clamping block 144 can slide along the guide groove 1211 into the clamping groove 1212, clamping and axially fixing the connecting member 12 in the accommodating tube 141, and the outer diameter of the connecting member 12 is less than or equal to the inner diameter of the accommodating tube 141, so that the inner side wall of the accommodating tube 141 and the outer side wall of the connecting member 12 abut against each other, providing support for the connecting member 12 and improving its durability.

[0019] The inner diameter of the connecting member 12 is less than or equal to the inner diameter of the push ring 142, so that when the connecting member 12 is clamped in the accommodating tube 141, the inner wall of the connecting member 12 is at most flush with the inner wall of the push ring 142, thereby reducing the gap when the shaving unit 20 is inserted into the connecting member 12 and reducing shaking.

[0020] A gap is left between the outer surface of the avoidance portion 122 and the inner wall of the accommodating tube 141, allowing room for deformation when the engaging protrusion 125 engages the shaving unit 20, thereby preventing the side walls of the connecting member 12 from directly contacting the side walls of the accommodating tube 141, which would otherwise cause engagement difficulties. In this embodiment, there are two avoidance portions 122, symmetrically disposed on either side of the connecting member 12.

[0021] The positioning protrusion 123 is arranged close to the outer wall of the clamping portion 121, so that one end surface of the positioning protrusion 123 is flush with the outer wall of the clamping portion 121. The positioning protrusion 123 is inserted and fixed between the limiting portion 143 and the inner wall of the accommodating tube 141 to radially fix the connector 12.

[0022] The positioning groove 124 and the limiting portion 143 are plugged and fixed to each other, and cooperate with the positioning protrusion 123 to achieve a limiting effect in two directions.

[0023] The engaging protrusions 125 are used to engage and secure the shaving unit 20, and a guide slope 126 is provided on the same side of the two engaging protrusions 125 along the rotation direction to guide the user in assembling the connector 12 with the shaving unit 20. It is conceivable that the guide slope 126 can be arranged in a clockwise or counterclockwise direction as required.

[0024] The shaving unit 20 includes a quick plug 21. The quick plug 21 comprises a quick plug body 211, at least one first guide slot 212 disposed on the quick plug body 211, at least one second guide slot 213 connected to the first guide slot 212, and at least one stopper 214 disposed near the second guide slot 213 near the first guide slot 212. When the stopper 214 abuts the engaging protrusion 125 in the connector 12, the clearance portion 122 elastically deforms, allowing the stopper 214 to more easily pass over the engaging protrusion 125 and engage with each other.

[0025] The outer diameter of the quick plug body 211 is smaller than the inner diameter of the abutting ring 142 , so that the quick plug body 211 can be inserted into the connecting member 12 .

[0026] The number of first guide grooves 212 and second guide grooves 213 should be equal. The first guide grooves 212 are positioned corresponding to the engaging protrusions 125, and the second guide grooves 213 are positioned adjacent to the guide slopes 126. A slope is provided at the intersection of the second guide grooves 213 and the first guide grooves 212 for further guidance. The stopper protrusions 214 are used to engage and secure the engaging protrusions 125, securing the shaving head 21 to the connector 12.

[0027] The power unit 30 includes a motor bracket 31 fixedly mounted on the quick-connect housing 11 , a spacer assembly 32 disposed between the motor bracket 31 and the quick-connect housing 11 , and a drive motor 33 disposed in the motor bracket 31 .

[0028] The motor bracket 31 has a gear slot 311 , a rotating shaft 312 disposed in the center of the gear slot 311 , and an output shaft hole 313 disposed on one side of the gear slot 311 .

[0029] The gasket assembly 32 includes a gasket 321 and a washer 322 embedded in the gasket 321. One end face of the gasket 321 is plugged into the motor bracket 31. When the motor bracket 31 is connected to the quick-connect housing 11, the gasket assembly 32 can achieve the purpose of sealing and waterproofing.

[0030] The output shaft of the drive motor 33 passes through the output shaft hole 313, driving a reduction gear (not shown) disposed in the gear slot 311. A gear shaft connects the reduction gear (not shown) to the shaving head 21, transmitting power from the drive motor 33 to the shaving head 21. It is contemplated that the drive motor 33 is connected to an external power supply for operation.

[0031] During use, the positioning groove 124 on the connector 12 is interlocked with the reinforcing rib 1432 to provide circumferential fixation, while the positioning protrusion 123 is inserted between the limiting rib 1431 and the accommodating tube 141 to provide radial fixation. When the positioning protrusion 123 abuts the abutting ring 142, the engaging block 144 slides along the guide groove 1211 into the engaging groove 1212, providing radial fixation, thereby completely securing the connector 12 in the accommodating tube 141. Next, the first guide groove 212 on the quick plug body 211 is aligned with the engaging protrusion 125. The plug body 211 is then rotated, causing the engaging protrusion 125 to slide along the second guide groove 213 until the limiting protrusion 214 passes over the engaging protrusion 125, completing the assembly of the shaving unit 30 and the quick-connect assembly 10. Finally, the power unit 30 is fixedly mounted on the quick-connect housing 11 , and the drive motor 33 is connected to a power source.

[0032] Compared with the prior art, the present invention provides a shaving device with a quick-connect structure. By setting the connecting member 12 in the quick-connect housing 11, the quick-connect housing 11 protects the connecting member 12 from being directly exposed to the outside, thereby improving the overall strength after assembly. A top ring 142, a limiting rib 1431, a reinforcing rib 1432, and a clamping block 144 are provided in the accommodating cylinder 141 to limit the axial movement and circumferential rotation of the connecting member 12. The two clamping protrusions 125 are provided on the avoidance portion 122. The avoidance portion 122 generates elastic deformation when subjected to force, thereby reducing the wear on the clamping protrusion 125 when the limiting protrusion 214 passes over the clamping protrusion 125, thereby extending the service life.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are included in the scope of the claims of the present invention.
